Where to put new sensor drivers?

Where to put new sensor drivers?

[Daniel Mack]

Hi,

I wrote a driver for an I2C connected ambient light sensor and submitted
it to the linux-i2c list[1]. In the first place, I wasn't aware of
drivers/i2c/chips being deprecated and hencei, I subsequently moved it to
what seemed to match best in the current tree, drivers/hwmon. But as
Jean Delvare pointed out, this is not the place for it either because it
doesn't really monitor the hardware, which is true.

So I posted a proposal[2] patch series that adds drivers/sensors for
such cases (some of the drivers in the legacy folder drivers/i2c/chips
have the same problem than my new one has) but haven't got reply on it
yet, probably because linux-i2c is the wrong place to ask.

Maybe someone here has an oppinon about that?


Thanks,
Daniel

Hmm, no feedback here either? I was pointed to the 'industrial I/O'
thread[1], but that one didn't go mainline yet, and I didn't find any
reference of someone picking up this idea.

Are such drivers not wanted in the kernel? I could also move my code to
userspace, but I though if it's supported by the kernel, more people
can acutally use it easily.

Well drivers/sensors sounds  sane. Or maybe drivers/senses :-).
